It operates at up to 8 MHz bus frequency, supports 2.7–5.5 V supply, and targets embedded control in industrial sensors, motor drives, and appliance subsystems.
For engineers reviewing the MC908AP16CFAE-NXP datasheet, MC908AP16CFAE-NXP pinout, MC908AP16CFAE-NXP application, or MC908AP16CFAE-NXP equivalent, this page provides verified technical context, package mapping, functional pin definitions, real-world use cases, and validated alternative options for design-in and supply continuity planning.
Technical Context
The MC908AP16CFAE-NXP implements the HCS08 CPU core with enhanced addressing modes, 16-level hardware stack, and low-power wait/stop modes. Its Clock Generator Module (CGM) integrates a PLL for flexible clock synthesis from internal RC or external crystal sources, enabling precise bus timing across voltage and temperature ranges.
System integration includes a System Integration Module (SIM) managing reset sources (POR, LVI, COP), interrupt prioritization, and SIM counter-based initialization sequencing. The Analog-to-Digital Converter features 8-channel, 10-bit resolution with programmable sample time and conversion trigger sources including timer overflow and external pin.

FAQ
What is the maximum operating frequency of the MC908AP16CFAE-NXP?
The MC908AP16CFAE-NXP supports a maximum bus frequency of 8 MHz, achieved via its integrated PLL-based Clock Generator Module (CGM). This frequency is sustained across the full 2.7–5.5 V supply range and industrial temperature grade (–40°C to +85°C), with timing specifications validated in the Freescale MC68HC908AP A-Family Data Sheet Rev. 3.
Does the MC908AP16CFAE-NXP include a hardware watchdog timer?
Yes, the MC908AP16CFAE-NXP includes a Computer Operating Properly (COP) watchdog timer with configurable timeout ranging from 0.5 ms to 1.6 s. It supports both standard and windowed modes to detect both stuck and runaway code execution, and is enabled by default after reset unless disabled via CONFIG register programming.
Can the MC908AP16CFAE-NXP perform in-system programming without external hardware?
Yes, the MC908AP16CFAE-NXP supports in-system programming via its on-chip Monitor ROM. Using the SCI interface and standard UART signals, firmware updates can be performed directly through the MC908AP16CFAE-NXP's serial port without requiring a dedicated programmer or debug probe - enabling field upgrades and factory programming flexibility.
What analog features are integrated into the MC908AP16CFAE-NXP?
The MC908AP16CFAE-NXP integrates an 8-channel, 10-bit successive-approximation ADC with programmable sample time, conversion triggers (timer overflow, external pin, software), and dedicated analog power pins (VDDA/VSSA) for noise isolation. No external ADC or reference is required for basic sensor interfacing tasks.
Is the MC908AP16CFAE-NXP pin-compatible with other members of the AP-family?
Yes, the MC908AP16CFAE-NXP shares identical 44-pin QFP packaging and pin assignments with MC908AP8A, MC908AP32A, and MC908AP64A. This allows direct substitution within the same footprint for capacity scaling - e.g., upgrading from 8 KB to 16 KB Flash requires only firmware and configuration register updates, not PCB redesign.
